New symbol short net on different layer

Filo221

Hi all, 

I would like to do a short between  two nets / plane on different layer.

The good solution could be a via, and use property "Net_short".

But I don't want to use the property "Net_short" and I have created a symbol  for to have more control on PCB.   

 

But it's not clear to me how I can do a vias in Allegro to connect two nets/plane both external and internal layer. 

I already tried some solutions but they don't work. 

Does anyone have any ideas?

Thanks

    A way to create a 'short' between two nets:

    create a eg rectangular SMD padstack on a certain etch layer.

    Shift the origin of the pad, thats where the cline will snap to. By using enough space between the origin points of the 2 padstacks, the clines (of different nets) will not touch eachother and won't create a DRC..

    Then create a footprint with 2 of these padstacks just touching eachother.

    Also add "NODRC_SYM_SAME_PIN" on the part so you don't get a DRC because of 2 padstacks touching eachother.

    I use a component such as a zero-ohm resistor to short two nets. Shorting two nets on a board creates a error for the fabricator. If someone insists on shorting two nets, set up a new subclass layer and name it something like "short". On the "short" layer, add a drawn line between two vias or pads. Add this subclass to the appropriate artwork under manufacturing/artwork. Please add a note to the fab drawing stating the two nets are intentionally shorted to help the fabricator know.
